Some patients develop tearing or watering eyes as a result of poor tear duct development during infancy or tear duct blockage over time. When the ducts are blocked, tears may overflow and back up into the eyes, blurring vision. The accumulation of non-draining tears can lead to an infection of the tear sac with redness and pain in the skin at the inner corner of the eye. This condition is often treated with antibiotics. If the tears do not drain normally down the ducts and into the nose, a new drain can be constructed. This is an outpatient procedure in which Dr. Agarwal makes a new opening from the tear duct into the nose, giving the tears the best chance for drainage and prevention of future infections.
